Design of an advanced intelligent instrument with waveform recognition based on the ITMS platform
Searching for similar behaviours in previous data plays a key role in fusion research, but it can be quite challenging to implement from a practical point of view. This paper describes the design of an intelligent measurement instrument that uses Similar Waveform Recognition Systems (SWRS) to extract knowledge from the signals it acquires. The system is perceived as an ethernet measurement ...

Choosing the correct Data Acquisition step for GPR
efore GPR surveying we have to set step of acquisition in Synchro program settings: We got different GPR profiles with different values of Step of acquisition. See the results below: Pipe3.sgpr GPR profile: Step of acquisition is 26,03 mm. Initial proportionality: one pixel is equal to one sample Pipe2.sgpr GPR profile: Step of acquisition is 156,18 mm. Initial proportionality: one ...

Method for irrigation scheduling based on soil moisture data acquisition
The water requirements of crops are dependent on evapotranspiration (ET), soil chemistry, and the crop’s maximum allowable depletion (MAD). Direct measurements of root zone soil moisture, water application along with published ET values and soil textures, can be used in a soil water balance model that can significantly optimize irrigation efficiency. Over the past five years, advancements in ...

Taxonomy of SCADA systems security testbeds
Considerable research has focused on developing simulation environments to study the effects of cyber–attacks on supervisory control and data acquisition (SCADA) systems although a methodology to develop a SCADA security testbed is not yet available. This paper attempts to address the issue by presenting a reference model taken from the literature and classifying specific contributions on the ...

Locating subverted processes using random packet comparison in SCADA systems
A supervisory control and data acquisition (SCADA) system may be subject to integrity attacks. Anomalies in sensor measurements may be used to detect these attacks, but such techniques do not permit us to locate attacking nodes. We propose a novel technique to enable this. Each participating network node probabilistically copies packets and marks them with routing information, before encrypting ...

Data Logger vs DAQ
Key Differences Between Data Logging and Data Acquisition What is the difference between a Data Logger vs DAQ System? A data logger is a type of data acquisition system, but a data acquisition system is not necessarily a datalogger. There are several key functional differences in how the market understands these two classes of instruments. While the differences between these two types of ...

Contributions of holography to the advancement of interferometric measurements of surface topography
Abstract Two major fields of study in optics—holography and interferometry—have developed at times independently and at other times together. The two methods share the principle of holistically recording as an intensity pattern the magnitude and phase distribution of a light wave, but they can differ significantly in how these recordings are formed and interpreted. Here we review ...
